Definition from Chambers - So as I read it Giron is the french spelling of Gyron. Which is comfirmed by my French/English dictionary.
Interesting, Aperio. But I don't think that this throws any new light on Saturday's dilemma.
On the wider question of whether the DT ever accepts alternative answers (as suggested by JimJools and other stalwarts) we shall have to wait for the published answers on Saturday. I think this is a vital issue for serious puzzlers, but don't hold your breath!
The interesting thing here is that g*ron is not a common word yet it appears twice within a matter of days in different newspapers. Is this a coincidence? Perhaps, the Times crossword compiler does the dtgk and is making a point?
Can't think of another example offhand, but this seems to happen quite often.
By the way, have any of you noticed that you have(apparently) lost the invitation to report my answers. Have the powers-that-be decided that they are always a) proper and b) pertinent? Or maybe that they are unlikely ever to be worth reporting. Either way, I take it as a rare distinction. :-)
